Use an Apple wireless trackpad
The Magic Trackpad and Magic Trackpad 2 support all of the trackpad gestures available on Apple portable computers. Both trackpads are larger than the trackpad on portable computers, so you have more room to perform gestures. You can perform gestures or click anywhere on the trackpad.
Before using an Apple wireless trackpad, you need to connect it with your Mac. See Connect an Apple wireless keyboard, mouse, or trackpad for more information.
